6-Benzylaminopurine: insider notes from the lab bench to the greenhouse

If you’ve walked through a modern micropropagation facility lately, you’ve probably heard technicians mention 6-Benzylaminopurine (some folks still say BA). It’s the quiet workhorse cytokinin behind uniform shoots, tighter production cycles, and—let’s be honest—fewer headaches when media behaves. From my conversations with buyers in Yuhua District to tissue-culture teams in Europe, demand hasn’t just held; it’s inching up as growers chase consistency and higher-value ornamentals.

Technical snapshot (real-world specs)

Name	6-Benzylaminopurine
CAS No.	1214-39-7
Molecular formula / weight	C12H11N5 / 225.25
Appearance	Off-white crystalline powder
Assay (HPLC)	≥ 99.0% (typical lots test 99.3–99.8%)
Water (KF)	≤ 0.5%
Melting point	≈ 230–235 °C
Solubility	Slight in water; soluble in DMSO/ethanol
Packaging / Shelf life	1 kg foil or 25 kg drum; 24–36 months sealed, cool/dry
Origin	No. 66 Xiangtai Road, Yuhua District, Shijiazhuang, Hebei, China

How it’s made and tested (short version)

Process flow: adenine derivative + benzylating agent → controlled nucleophilic substitution → purification (multi-step recrystallization) → drying under reduced pressure → QC release.

• Methods: HPLC assay; IR/NMR identity; KF moisture; residues per ICH Q3C.
• Standards referenced: ISO 9001 QA system; OECD TG 105 (solubility) and TG 301 (biodegradability, when assessed); EPA PGR guidance.
• Service life: stability maintained when sealed, protected from UV; real-world use may vary after repeated jar openings.

Where it’s used (and why buyers care)

• Plant tissue culture: shoot induction in bananas, orchids, blueberries—clean nodes, fewer vitrification complaints when media pH is on point.
• Horticulture and seedling trays: tighter internodes, more uniform plugs.
• Research: cytokinin pathway studies; protocol optimization alongside IAA/NAA.

Advantages of 6-Benzylaminopurine vs alternatives? Consistent shoot proliferation, relatively predictable dose-response, and broad compatibility. Many customers say it’s “boringly reliable”—which is exactly what you want at scale.

Customization and packaging

• Grades: culture-grade, technical-grade; documentation pack (COA, MSDS, TDS, method sheet).
• Particle size control for faster dissolution; pre-weighed sachets for media rooms.
• Labeling and palletization per customer SOP; batch retain samples available.

Vendor comparison (quick glance)

Vendor	Purity (HPLC)	Docs & Certs	MOQ	Lead time	Customization
Hebei supplier (this listing)	≥99.0% (typ. 99.5%)	COA, MSDS; ISO 9001; third-party HPLC on request	1 kg	7–12 days ex-works	Yes (pack size, particle size)
Vendor A (importer)	≥98.0%	COA; basic MSDS	5 kg	2–4 weeks	Limited
Vendor B (lab catalog)	≥99.0%	COA; lot traceability; ISO 17025 partner lab	100 g	Stock-dependent	Small-pack only

Case notes and feedback

• Berry lab (EU): switch to 6-Benzylaminopurine with tighter particle spec cut dissolution time ≈15%, fewer filter clogs—simple but helpful.
• Orchid grower (SEA): “Shoot count up, vitrification down after we adjusted pH and BA levels.” Not magic, just good housekeeping.

Compliance and data points

Lots are HPLC-verified with retention-time match to a certified reference. Safety data follow GHS; environmental data (where required) align with OECD guidelines. For agricultural registrations, check local EPA/FAO listings; rules differ by country, and, to be honest, they do change.
